Thanks, this video is exactly what I was looking for. A clear explanation. Sorta rare. Well done.

Tony I've been working on my own rental properties for twenty years and I want to mention that when I find a chrome plated copper line I usually leave it in there. I can't remember one failing ever. I have had a couple of stainless steel braided supply lines burst during that period of time and was lucky to either have it happen in a place that did not cause damage or have a quick thinking tenant (which in and of itself is a miracle) who shut the valve quickly. My advice would be to replace the s steel braided lines at least every seven years. Eventually they will leak and maybe burst.

It's my first time replacing the flushing system and the toilet water supply hose. It looked easy from watching Youtube videos but I struggled with old parts and marrying old with new. By watching your video, ideas sparked. Thank you.

Thanks. A good video to ensure I connected the braided supply lines for for my new basement utility sink correctly to the supply lines and valve fittings I had a contractor plumb in for that sink.

Thanks so much. You are the best. All other Youtube plumbers only demonstrate with the new thread supply line. They don't deal with the past. I have an old house. The supply lines don't look like those new thread ones. So I was so confused.

Thanks, this was a really clear video, and I love that you basically cursed the plumbing of anyone who doesn't like and subscribe. 😆

My question is, I am not sure if they are making them cheaper, nowadays every time I change the faucet and a toilet, I end up changing the supply line. Today I changed my faucet and supply line would not stop leaking. So I went to buy a new and it stopped leaking. I don’t get it?

Tony, should teflon tape be used on the threads for the braided steel supply line connections?

[Rae_Mah_Boo]

And these sink hoses, plastic/metal, interchangeable? For example, could I replace my plastic pex with the metal one?

My cold supply line to my kitchen faucet doesn't have a rotating nut on the shutoff valve side. Is there a way to reconnect it with another fitting without replacing the whole line? I'm installing an RO water filtration system and I had to disconnect that supply line to add the feed water adapter under it. Along with an 1/2 to 3/8 adapter (3/8 male into the supply line with no rotating nut so I would be kinking the hose and fighting against it). Thanks!

The only braided line used in my house failed and flooded. I'd never use it again. There are lots of others who have had similar experiences. You can find other videos here on YouTube with the same experience.

If I can't disconnect a line under the bathroom sink valve because of corrosion, are there 1/2 inch to 1/2 inch extender supply lines available that don't require compression-to-compression connection fittings? Specifically, I need an extender to connect to an existing 1/2 inch connection, the 3/8 is already connected to the valve I don't want to remove either the old valve or the line. Hope this makes sense.

Tony, our home was built in the late 1990s and the builder had used Supply line which is about the diameter of a pencil, some sort of very hard but flexible plastic material. Anyway, one of the faucet shutoff valve went bad and I took the Supply Line to Hardware store and they said you need to change these lines in your entire home 'cause the chlorine in the water corrodes them and disaster is just waiting to happen. Is this correct? They withstood well over two decades without any issue though.

I installed a toilet hose with plastic nut. I failed to keep it from twisting by not holding it with back wrench. It broke and made a mess. Lucky we were home.

[BrianHorton]

If my supply line is 3/4”, can I transition to a 1” and get the benefit of additional flow, or am I stuck with 3/4” max all the way through?

[bluearcherx]

supply line 201: i have a vintage 1930s bathroom, I want to use 3/8 OD chrome plated copper risers for the aesthetic. obviously compression fitting at the stop, but I am not sure what kind to get for 1/2" NPS faucet connection.. straight threads. Do I just get a bullnose for this and tighten it down w/o tape or sealant?

[upshiftgo]

I just installed a new dishwasher with a new steel braided hose and immediately after our sink tap water started to taste like a new hose. Are there hoses that don’t have such a bad taste when new like typical hot water sink hoses?

[theo]

How tight do you have to get the newer metal braided lines with compression fitting? I read it's just a quarter turn past hand tight but I don't think that is true because I still have a small leak coming from the 3/8ths connection that attaches directly to the hot supply shut off valve. I don't want to crank down on it more without asking. It's tight but I could still turn the nut more if need be. I don't want to cause another bigger leak if I can help it. And these don't require plumbers tape either correct?

[RichardSinek]

Great information but where can I get one of those extenders you talked about around the 9 minute mark? I got a laundry sink and faucet with built in hoses - like a kitchen faucet but they are about 3-4" too short. I can't find extenders at hardware or big box stores and the ones on Amazon have 3/8 on one end but M10 on the I have not found 3/8M to 3/8F.
